Problems solved by technology

[0005] In view of this, the present invention provides a pipeline joint, transmission pipeline and transmission system to solve the large deformation of the pipeline caused by the movement of the fault in the earth's crust. When the fault moves, the soil layer in which the pipeline is buried will move accordingly; The technical problem that the pipeline is prone to fracture due to the force of the soil layer

Abstract

The invention provides a pipeline joint, a conveying pipeline and a conveying system. The pipeline joint comprises a front connecting pipe, a rear connecting pipe and a corrugated pipe. The front endof the front connecting pipe is used for communicating with a front-section pipeline, and the rear end of the front connecting pipe communicates with the first end of the corrugated pipe. The front end of the rear connecting pipe communicates with the second end of the corrugated pipe, and the rear end of the rear connecting pipe is used for communicating with a rear-section pipeline; when the fault of the earth crust moves, the corrugated pipe is subjected to elastic deformation after being subjected to bending moment, so that the bending moment borne by the front-section pipeline and the rear-section pipeline is reduced, and then the front-section pipeline and the rear-section pipeline are prevented from being bent and broken.

Description

technical field [0001] The invention relates to the technical field of oil and gas transportation equipment manufacturing, in particular to a pipeline joint, a transportation pipeline and a transportation system. Background technique [0002] With the gradual maturity of oil and natural gas extraction and detection technology, more and more oil and gas are extracted and processed, and the distance between the location of oil and gas wells and the factories that process oil and gas, as well as between the factories and users of oil and gas is often longer , so how to transport oil and gas has become a research hotspot. [0003] In the prior art, because oil and gas are flammable items, the risk of transporting oil and gas through transportation is relatively high, so oil and gas are often transported through pipelines buried underground; pipelines are generally formed by welding multiple steel pipes, that is, the rear of the previous steel pipe. The end and the front end of ...
